dryriver writes "The BBC reports that cosmetic products using bee venom as an ingredient are a new 'hot seller' in the cosmetics market. Bee venom is said to have an effect on female skin similar to Botox injections, tightening the skin and making wrinkles and other signs of aging appear less pronounced than before. Unlike Botox, however, bee venom does not need to be injected, and can be absorbed through the skin naturally as an ingredient of cosmetic skin creme. Now comes the kicker: A special electrified device that causes bees to sting a synthetic membrane and release their venom can harvest about one gram of bee venom from 20 bee hives. That one gram of bee venom is worth a whopping 350 dollars. This makes bee venom almost seven times more valuable than gold, which, in comparison, is worth only about 53 dollars per gram."

New submitter dgrobinson writes "NY Times reports that West Antarctica has warmed more over the last half century than was first thought. A paper released Sunday by the journal Nature Geoscience (abstract) found that the temperature at a research station in the middle of West Antarctica has warmed by 4.4 degrees Fahrenheit since 1958. That is roughly twice as much as scientists previously thought and three times the overall rate of global warming, making central West Antarctica one of the fastest-warming regions on earth."

SternisheFan writes with a snippet from Science Recorder: "Reporting in the journal Geochimica et Cosmochimica Acta, researchers at Brigham Young University say that the Hawaiian Islands are slowly dissolving. Eventually, Oahu's Koolau and Waianae mountains will dwindle to little more than a flat, low-lying island like Midway. While erosion is certainly a guilty party, researchers contend that the mountains of Oahu are, in fact, dissolving from within. Researchers spent several months collecting samples of groundwater and stream water to determine which source removed more mineral material. They also put to use surface water estimates from the U.S. Geological Survey to calculate the quantity of mass that vanished from the island each year. Researchers point out that Oahu is actually rising in elevation at a slow but steady rate due to plate tectonics. [BYU geologist Steve Nelson] and colleagues believe that Oahu will continue to grow for as long as 1.5 million years. Beyond that, the force of groundwater will eventually win and Oahu will begin its transformation to a flat, low-lying island like Midway."

dryriver writes with a report from CNN that the asteroid known as 2011 AG5will not hit Earth in 2040 as early calculations had led some to fear when it was first spotted last year. "To narrow down the asteroid's future course, NASA put out a call for more observation. Astronomers from the University of Hawaii at Manoa took up the task and managed to observe the asteroid over several days in October. 'An analysis of the new data conducted by NASA's Near-Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, California, shows that the risk of collision in 2040 has been eliminated,' NASA declared Friday."

resistant writes "A limited study from China offers the tantalizing possibility that targeting specific gut bacteria in humans could significantly reduce the scope of an epidemic of obesity in Western countries: 'The endotoxin-producing Enterobacter decreased in relative abundance from 35% of the volunteer's gut bacteria to non-detectable, during which time the volunteer lost 51.4kg of 174.8kg initial weight and recovered from hyperglycemia and hypertension after 23 weeks on a diet of whole grains, traditional Chinese medicinal foods and prebiotics.' As usual, sensationalist reports have been exaggerating the import of this very early investigation, and one wonders about that 'diet of whole grains.' Still, there could be meat in the idea of addressing pathogenic bacteria for the control of excessive weight gain. After all, it wasn't too long ago that a brave scientist insisted in the face of widespread ridicule that peptic ulcers in humans usually are caused by bacterial infections, not by acidic foods."

theodp writes "The BBC News' Laura Gray reports on a juggling notation system developed in the 80's called Siteswap (aka Quantum Juggling and Cambridge Notation) and how it has helped jugglers discover and share thousands of new tricks. Frustrated that there was no way to write down juggling moves, mathematician Colin Wright and others helped devised Siteswap, which uses sequences of numbers to encode the number of beats of each throw, which is related to their height and the hand to which the throw is made. 'Siteswap has allowed jugglers to share tricks with each other without having to meet in person or film themselves,' says James Grime, juggling enthusiast and math instructor for Cambridge University. Still unclear on the concept? Spend some time playing around with Paul Klimek's most-excellent Quantum Juggling simulator, and you too can be a Flying Karamazov Brother!"

An anonymous reader writes "One of the most powerful supercomputers in the world has now been fully installed and tested at its remote, high altitude site in the Andes of northern Chile. It's a critical part of the Atacama Large Millimeter/submillimeter Array (ALMA), the most elaborate ground-based astronomical telescope in history. The special-purpose ALMA correlator has over 134 million processors and performs up to 17 quadrillion operations per second, a speed comparable to the fastest general-purpose supercomputer in operation today."

Hugh Pickens writes "Jamal Khan reports that the United Nations has suspended its polio vaccination drive in Pakistan after eight people involved in the effort were shot dead in the past few days. The killings dealt a grave blow to the drive to bring an end to the scourge of polio in Pakistan, one of only three countries where the crippling disease still survives. Militants accuse health workers of acting as spies for the U.S. and claim the vaccine makes children sterile. Taliban commanders in the troubled northwest tribal region have also said vaccinations can't go forward until the U.S. stops drone strikes in the country. Insurgent opposition to the campaign grew last year after it was revealed that a Pakistani doctor ran a fake polio vaccination program to help the CIA track down and kill Osama bin Laden, who was hiding in the town of Abbottabad in the country's northwest. The Pakistani government has condemned the attacks against aid workers, saying they deprive Pakistan's most vulnerable populations — specifically children — of basic life-saving health interventions. A total of 56 polio cases have been reported in Pakistan during 2012, down from 190 the previous year, according to the U.N. Most of the new cases in Pakistan are in the northwest, where the presence of militants makes it difficult to reach children. Clerics and tribal elders were recruited to support polio vaccinations in an attempt to open up areas previously inaccessible to health workers. 'This is undoubtedly a tragic setback,' says UNICEF spokeswoman Sarah Crowe, 'but the campaign to eradicate polio will and must continue.'"

Lasrick writes "For the first time since 1946, Congress is seriously debating whether the U.S. nuclear weapons complex should be under civilian or military control. That the article is in the Bulletin of Atomic Scientists is significant, as it was many of the scientists who founded BAS who argued for civilian control in the wake of Hiroshima and Nagasaki. They believed that atomic energy was too destructive, and the military too secretive, which would possibly thwart scientific discovery and erect a major obstacle to international control and cooperation. The article talks about how management has changed over the decades and explains the discussion that needs to happen before Congress acts."

SternisheFan sends this excerpt from Space.com:
It might make the astronaut wearing it look like a real-life Buzz Lightyear, but a new prototype spacesuit that NASA just finished testing represents the first major overhaul in spacesuit technology since 1998. Flexible, white, and lime green accented, the suit — known as the Z-1 — is designed not only to help astronauts comfortably maneuver during spacewalks in microgravity, but also to deftly move about when walking on the surface of a planet or other smaller heavenly body, like an asteroid. [Engineer Amy Ross] said, 'the shuttle EMU splits at the waist and you put pants on and you put the top on separately and they connect in the middle. Whereas with this suit, the subject crawls in through the back, and then we just shut the door.' Creating a back-entry suit solves a few of the problems spacewalkers often face during trips to the International Space Station. Using airlocks to depressurize is a time consuming, exhausting process. By using a back-entry design, the astronauts won't need to go through an airlock at all. The suit hooks up to the outside of the spacecraft using the "space port" opening, and the spacewalker simply climbs in and detaches."

An anonymous reader writes in with a story about the possibility of having another you in the future. "Human cloning could happen within the next half century, claims a Nobel Prize-winning scientist. Sir John Gurdon, the British developmental biologist whose research cloning frogs in the 1950s and 60s led to the later creation of Dolly the sheep in 1996, believes that human cloning could happen within the next 50 years. He said that parents who lose their children to tragic accidents might be able to clone replacements in the next few decades. Gurdon, who won this year's Nobel Prize for Physiology or Medicine, said that while any attempts to clone a human would likely raise complex ethical issues, he believes that in the near future people would overcome their concerns if cloning became medically useful."

They are capable of delicate surgery, creating beautiful works of art, and comforting someone feeling down, but according to a new study your hands evolved to smash someone in the face. From the article: "Human hands evolved so that men could make fists and fight, and not just for manual dexterity, new research finds.
The study, published in the Journal of Experimental Biology, adds to a growing body of evidence that humans are among the most aggressive and violent animals on the planet.
'With the notable exception of bonobos, great apes are a relatively aggressive group of mammals,' lead author David Carrier told Discovery News. 'Although some primatologists may argue that chimpanzees are the most aggressive apes, I think the evidence suggests that humans are substantially more violent.''"

alphadogg writes "Researchers at MIT and other institutions have demonstrated a new type of magnetism, only the third kind ever found, and it may find its way into future communications, computing and data storage technologies. Working with a tiny crystal of a rare mineral that took 10 months to make, the researchers for the first time have demonstrated a magnetic state called a QSL (quantum spin liquid), according to MIT physics professor Young Lee. He is the lead author of a paper on their findings, which is set to be published in the journal Nature this week (abstract). Theorists had said QSLs might exist, but one had never been demonstrated before. 'We think it's pretty important,' Lee said, adding that he would let his peers be the ultimate judges."

skade88 writes "Do you remember those large TI-8X line of calculators with a BW display from when you were growing up and learning all about math? Yeah well, you can still get them because TI has yet to update or change their line of TI-8X calculators from their 96x64 display, processors designed in the 1980s with just a few kilobytes of user accessible memory. They still cost in the $100.00 to $150.00 range. That is all about to change now that the TI-8X line of calculators is 22 years old. Their new TI-84+C-Silver edition will come with a 320x240 16-bit color display, 3.5MB of flash ROM, and 21KB of RAM. Ars has a good preview of the device along with speculation on why it took so so so very long for TI to finally bring calculators up to a level of technology that could have been delivered a decade ago."Last month some photos and a few details of the new TI-84+C were leaked.
